In the utility model running, the inner heat producing can outwards be evacuated by gas channel, it is little that the increase of ventilating heat dissipating hole makes high-voltage switch gear in-cabinet temperature and high-tension switch cabinet external environment temperature and humidity thereof change difference, prevent that the globule phenomenon of condensing from occurring, and extended the life-span of insulating part.In addition, pressure release cover plate is flexibly connected with pressure release supporting bracket, and while breaking down in high-voltage switch cabinet, gases at high pressure are easy to pressure release cover plate to wash open, release pressure, assurance operating personnel's safety.
Preferably, ventilating heat dissipating hole and ventilating window place are also provided with Air Filter, prevent that extraneous too much dust from entering in the compartment of each high-tension switch cabinet, are scattered in and on insulating part, cause insulation short circuit.
Preferably, described ventilating window position is shutter, and ventilating window is the folding degree between adjusting vane arbitrarily, in the situation that air-flow is larger, can pass through by rapid, high volume, in case air-flow is excessive, and damage equipment.
Compared with prior art, the utlity model has following beneficial effect:
The utility model is provided with many places ventilating window and ventilating heat dissipating hole on high-tension switch cabinet body, can make the inner heat producing in high-tension switch cabinet running be evacuated in time, prevent that condensation phenomenon from occurring, extend the useful life of interior each insulating part of high-tension switch cabinet and components and parts, simultaneously Air Filter can prevent that extraneous too much dust from entering in high-tension switch cabinet, is scattered in and on insulating part, causes insulation short circuit.In addition, pressure release cover plate is flexibly connected with pressure release supporting bracket, and while breaking down in high-voltage switch cabinet, gases at high pressure are easy to pressure release cover plate to wash open, release pressure, assurance operating personnel's safety.
